iPECIFICATION forming part of Letters Patent No. 346,077, dated July 20,1886.

Application tiled February 11, 1886. Serial No. 191,528. (No model.)

To all whom, it may concern;

Be it known that 1, CHARLES A. VAILE, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Sl ylights, of which the following is aspecification.

My invention relates to certain improvements in skylights, which arehereinafter described and claimed.

In the accompanying drawings, which illustrate the invention, Figures 1to 7 illustrate the progressive steps in the formation of my improvedsheet-iron cap with attached sheetlead packing'strip. Fig. Sis across-section of the skylightbar, glass plates, and cap.

In. constructing the improved cap A, (see Figs. 7 and 8,) so that itshall have a sheet lead packing-strip, I), attached at the base of eachsloping side, a strip, A, of galvanized sheet-iron, in the fiat, has itstwo parallel edges turned up and partly over, as at c, Fig. l. The upperside (shown in Figs. 1, 2, 3, and l) becomes the lower or inner side ofthe finished cap. Two strips, 12, of sheet-lead, are laid on thesheet-iron A--one lead strip in contact with each turned-up edge 0. Thesaid turned up edges 0 are then flattened down against the lead strip1), so as to inclose each, as shown in Figs. 3 and 4. Indentations e arethen made in the flattened iron edge 0 by means ofa prickpunch orsimilar tool. By these indentations the metal of the iron part isimpressed or embedded into the metal of the lead part, and thereby thelead strips b are firmly attached to the iron A. The free edge at of thetwo lead strips is next turned away from each other and over upon theflattened iron edge 0, as shown in Figs. 5 and 6. The iron strip A nowhas attached to it the two lead strips, and said iron strip is bentalong a line centered between the two lead strips, and thereby forms twosloping sides, and comprises the cap A, having the shape shownin Fig. 7.It will be seen the free edge d of each lead packing-strip projectslaterally from below the base of one of the sloping sides of the cap.

The lead packing-strips are attached to the cap, as above described, atthe factory, and the finished cap thus provided may be sent any distanceto where the skylight is to be put up.

The lower bars, G, support the glass plates H, and the improved cap A isplaced above the glass plates and over the said supportingbar. The freeedge (1 of the lead packing-strip is flexible, and is readily seatedupon and close in contact with the glass plate. As the lead strip isrigidly attached to the iron cap, the free edged may be bent, depressed,or manipulated to fit close against the glass H, and will remain asadjusted. No other packing-such as rubber, putty, or cementis required.

The lower bars, G, are bent to have a shape in crosssection, similartoaletter W, whereby two gutters, f f, are formed for the collection ofleakage water or the condensation of moisture on the glass. Two guttersprovidea double security against the annoyance of water.

The two lower bars, G, are the edges of a single plate or strip, whichis bent or folded at g on a central line. The folded part constitutes avertical rib, h, and each bar G is sus pended at the lowermost part ofsaid rib.

The cap A has slots 2' made in the usual manner, and strips of metal 75,secured to the vertical rib h by rivets Z, pass up through the saidslots i in the cap, and are bent sidewise to hold the cap in position.

From the drawings and description given of the cap and its attachedsheet-lead strips, it will be understood the edge 0, at the base of eachslope of the cap, is turned up inward, and one edge of the sheet-leadstrip is folded tightly in one of said turned-up edges, and theresecured, while the free edge d of the said strip projects laterally frombelow the base of the slope. Thus the lead strip forms a seat for thecap A, and the laterally projecting edge d of the lead is soft andsufficiently pliable to be pressed close to the glass plate H, andthereby exclude rainwater. An advantage of the lead strip thus rigidlyattached to the iron cap A is that it may have its laterally'projectingedge (1 pressed close to the glass plate at any uneven place therein,and whenever thus depressed the lead will retain its position.

WVhile the cap is herein described as being made of sheet-iron, it isobvious it may be made of sheet copper, zinc, or any other metal.

Having described myinvention, I'claim and desire to secure by LettersPatent of the United States- 1. A skylight-cap, A, comprising asheetmetal strip having sloping sides and provided strips having oneedge folded tightly in said 10 at the base of each sloping side with arigidlyinward-turned edges and projecting laterally attached sheetleadpacking-strip, which profrom below the base of the sides, as set forth.jects laterally from below the base of the side, In testimony whereofIaffix my signature in as set forth. the presence of two witnesses.

2. A skylight-cap, A, comprising a sheet- CHARLES A. VAILE. metal striphavingslopingsides, and the edges 0 at the base of the sides turned upinward parallel with said sides, and sheet-lead packing- Witnesses:
